Hello all, I come again in my time of need.
I've recently came by some ball screws for my homebrew CNC mill but the output shafts on my stepper motors are much smaller than the ball screw shafts and the shafts on my stepper motors are geared. Does anybody know a coupling solution for mismatched shaft sizes? I know I could just drive the screws with belts, but I would prefer to couple my motors directly to the scerw shafts. Also, does anybody know a good way to remove the gears from my motor shafts?
